Usain Bolt
wants to reassure his fans he's not a PED-abusing cheater ... after two
of his biggest rivals tested positive for banned substances.
Bolt
-- the fastest man on the planet (BY FAR) -- addressed the media in
London today in the wake of the juicing busts of his Jamaican teammate Asafa Powell and American runner Tyson Gay.
"It's going to set us back a little bit but as a person I can't really focus on this," Bolt said.
"I was made to inspire people and to run. I have confidence in myself and my team. I KNOW I'M CLEAN so I'm just going to continue running and try to improve the sport. That's my aim."
Bolt
says his track record shows he's dominated the sport for years and
insists there's no greater piece of evidence than hard numbers -- "If
you had been following me since 2002, you'd know I've been doing
incredible things since the age of 15."
